IMPROVEMENT IN TOV THAUMATROPES.

Specification forming part of Letters Patent No. [83,550, dated October 24, 1876; application filed October 11, 1876.

To all whom it may concern :l

Be it known that I, WILLIAM H. EARLE, of

y Georgetown, in the county of Washington and District of Columbia, have invented certain new and useful Improvements in Thaumatropes; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l is a side view of my invention. Fig. 2 is an end view. Fig. 3 is a sectional elevation, and Fig. 4 is a side view of one of the picture-cards.

A is the frame for holding the cards. A are the standards, in which are notches or slots c a, in which the pivots a of the cards are sustained and revolve freely.v B is a handle, by which the device is held. C is an arm of thin metal, extending at right 'angles from the middle of the frame A, on which is fastened a block, D, having a small hole in it for the end of a blow-pipe, E. F represents one of a series of cards, onA one side, F1, of which is any suitable pictorial 'representa/tion, while on the opposite side (Fi, Fig. 4) is another pictorial representation, the' two being so arranged relatively that when revolved with a certain Ydegree of rapidity the two pictures appear to the eye of the observer to be but one representation," as in the present gures one of thedogs-tppears to be standing on the chair with hind feet, and his fore-paws on the table. l

This method of representation is well known but originally the picture-card was twirled around by means of strings properly arranged; also, the picture has been hun g inL a frame continued around it in a circle, and a pipe, for

blast, placed o n top; but the person blowing into it could not himself see the picture.

Others, again, use the breath only, without a -1. In thaumatropes, the frame A, with open l slotted standards A', in combination with a revolving and removable picture-card, substantially as and for the purpose described.

2. The removable blow-pipe, in combination with the frame A and revolving cards, substantially as and for the purpose described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

WM. H. EARLE.
